I want to know about the Mariana Trench

Located at 11 ° 20 N, 142 °,That is, the northeast of the Philippines, the Pacific Ocean floor near the Mariana Islands, from Iwo Jima in the north to Yap Island in the southwest. It has the Aleutian, Kuril Island, Ogasawara and other trenches in the north, and the New Britain and New Hebrides trenches in the south, with a total length of 2,550 kilometers, an arc, and an average width of 70 kilometers. It is estimated that the trench has been formed for 60 million years.

At its deepest point, 6,11 kilometres, it is the deepest known ocean, and it is one of the harshest areas on Earth due to its high water pressure, complete darkness, low temperatures, low oxygen levels and lack of food resources.

Benthos. If the world's highest mountain, Mount Everest, is placed at the bottom of the ditch, the summit will not be able to expose the water. Many mountaineers have successfully conquered Mount Everest, but it is extremely difficult to explore the deep sea. In January 1960, scientists successfully dived to the bottom of the Mariana Trench for the first time aboard the deep-sea submersible "Trieste" for the first time.

The huge water pressure of up to 1,100 atmospheres at the bottom of the trench is a huge challenge for humans.

The deep sea is a high-pressure, dark and icy world, with a temperature of only 2 (a very small number of seafloors can reach water temperatures of up to 380 due to geothermal influence). Amazingly, at such a deep seabed, scientists saw a flounder and a small red shrimp swimming. Some theories suggest that deep-sea trenches are mainly caused by violent depressions in the earth's crust.

The Mariana Trench, the deepest place in the world, has strange fish living in the trench.

Can the Mariana Trench, the deepest trench in the world, really reach the center of the earth?

What exactly exists at the bottom of the Mariana Trench?

The Mariana Trench is located between the Asian continent and Australia, from the Iwo Islands in the north to Yap Island in the southwest, between 11°20 north latitude and 142° east longitude, roughly located in the northeast of the Philippines, near the Mariana Islands at the bottom of the Pacific Ocean

The Mariana Trench has the Aleutian, Kuril and Ogasawara trenches in the north, and the New Britain and New Hebrides trenches in the south, with a total length of 2,550 kilometers and an arc shape with an average width of 70 kilometers. It is estimated that the trench has been formed for 60 million years.

The Mariana Trench is not only the deepest known ocean, but also a plate subduction zone, with very active geological movements on the seafloor, making it one of the harshest environmental areas on Earth.

Causes of the formation of the Mariana Trench

It is generally believed that the oceanic plate collides with the continental plate, and because the oceanic plate has a high density of rocks and a low position, it subducts under the continental plate, and the plate gradually melts and disappears after entering the mantle.

Ocean trenches are formed where collisions occur, and island arcs, back-arc basins, and coastal mountains are often formed on the side close to the mainland. These are areas of intense geological activity, with frequent volcanic eruptions and **.

It is located at 11°20 N, 142°, that is, the bottom of the Pacific Ocean near the Mariana Islands, from Iwo Jima in the north to Yap Island in the southwest. It has the Aleutian, Kuril Island, Ogasawara and other sea trenches in the north, and the New Britain and New Hebrides trenches in the south, with a total length of 2,550 kilometers, which is a simple arc of knowledge and difficulty, with an average width of 70 kilometers.

Western pacific. Mariana Trench (Mariana Trench, also known as: Mariana Trench), is located in the northeast of Chunchong in the Philippines, at the bottom of the Pacific Ocean near the Mariana Islands, from Iwo Jima in the north to Yap Island in the southwest.

Mali Rock shouts Ya Yu Shan Na Trench, also known as"Mariana Islands Trench"It is the deepest known ocean trench on Earth, located on the seabed of the western North Pacific Ocean, near the eastern part of the Mariana Islands.

option b Western North Pacific.

The Mariana Trench is located in the western Pacific Ocean, that is, the northeast of the Philippines, the bottom of the Pacific Ocean near the Mariana Islands, from Iwo Jima in the north to Yap Island in the southwest.

There is a mysterious and terrifying place on the earth we live in, and this is the Mariana Trench, the deepest part of the earth.

It is located in the eastern part of the Mariana Islands in the western Pacific Ocean, and the terrain structure presents a huge V-shape, the Mariana Trench extends longitudinally up to 15,000 meters and the depth is more than 11 kilometers, and the world's first peak, Mount Everest, can easily be put into this almost bottomless abyss!

In 1985, Soviet scientists found signs of life at a depth of 7,000 meters, and since then there is growing evidence of a large amount of life in the Mariana Trench.

They found invertebrates and mollusks in addition to bacteria, and perhaps prehistoric creatures in the deepest places.

In 1960, scientists began to use submarines to dive into a dark area at an altitude close to minus 11,000 meters, and the atmospheric pressure was equivalent to 1,100 times that of sea level, and carried out a 20-minute scientific expedition, discovering a large number of life activities, which caused a sensation around the world at that time.

You must know that steel will deform in the face of this pressure, but huge mussels and strange-looking fish can live here unharmed.

After several dives, biologists have speculated that they have found signs of activity in the prehistoric Megalodon, which is the ancestor of all sharks today, weighing 50 tons and measuring about 22 meters long, according to available fossils.

If they do exist, then the Mariana Trench would be their perfect hiding place. If this is true, then the presence of unidentified creatures on the ocean floor seems to explain it.

However, this speculation has not been confirmed, and the truth of the matter has only slowly surfaced as the scientific exploration continues.
